Bow Shock and Upstream Phenomena at Mars [PDF]
Space Science Reviews, 2004 Mars Global Surveyor is the sixth spacecraft to return measurements of the Martian bow shock. The earlier missions were Mariner 4 (1964), Mars 2 and 3 (1972), Mars 5 (1975) and Phobos 2 (1989) (see reviews by Gringauz, 1981; Slavin and Holzer, 1982; Russell, 1985; Vaisberg, 1992a,b; Zakharov, 1992).

Reflection of the strahl within the foot of the Earth's bow shock [PDF]
Annales Geophysicae, 2019 The reflection of a fraction of the solar wind at the bow shock to some extent defines the physical properties of what is known as the foreshock, the region where the interplanetary magnetic field has a direct connection to the bow shock.

Bow shock motions observed with CLUSTER [PDF]
Geophysical Research Letters, 2003 The Cluster mission allows the determination not only of the bow shock crossing position but also, with a simple timing method and a reasonable confidence, the shock normal and the velocity along this normal. We apply this technique to a series of eleven consecutive bow shock crossings which occurred during a time interval of approximatively two and a ...

A model of the magnetosheath magnetic field during magnetic clouds [PDF]
Annales Geophysicae, 2014 Magnetic clouds (MCs) are huge interplanetary structures which originate from the Sun and have a paramount importance in driving magnetospheric storms. Before reaching the magnetosphere, MCs interact with the Earth's bow shock.

HH 34: The Bow Shock of a Jet [PDF]
Symposium - International Astronomical Union, 1987 Deep CCD imaging of HH 34 in H∝ shows that the HH-object has a bow shock-like structure, of which the wings can be traced over about 1 arcmin ( pc). A knotty jet is pointing towards the apex of the bow shock structure. Long-slit spectroscopy reveals that 1) the jet has approximately a constant radial velocity and electron density. 2).

Multispacecraft observations of the terrestrial bow shock and magnetopause during extreme solar wind disturbances [PDF]
Annales Geophysicae, 2012 Three events are discussed from the declining phase of the last solar cycle when the magnetopause and/or the bow shock were observed unusually close to the Earth due to major interplanetary disturbances.

HD 189733 b: bow shock or no shock? [PDF]
Astronomy & Astrophysics, 2018 Context. Hot Jupiters are surrounded by extended atmospheres of neutral hydrogen. Observations have provided evidence for in-transit hydrogen Hα absorption as well as variable pre-transit absorption signals. These have been interpreted in terms of a bow shock or an accretion stream that transits the host star before the planet. Aims.

Journal of Space Weather and Space Climate, 2018 We have used the AMR-CESE-MHD model to investigate the influences of the IMF Bz and the upstream solar wind dynamic pressure (Dp) on Earth’s magnetopause and bow shock.

Properties and the origin of Almost Monoenergetic Ion (AMI) beams observed near the Earth's bow shock [PDF]
Annales Geophysicae, 2011 Beams of Almost Monoenergetic Ions (AMI) in the energy range from 20 to 800 keV were discovered in the DOK-2 experiment (Interball project) in the magnetosheath and upstream of the Earth's bow shock.
